[codex] Add provider boundary checklist

[Radical-Coder]

What changed

Adds a BOUNDARY CHECKS section that explains what production readiness means in Ryan's actual delivery work:

• Stripe payment state and webhook reconciliation
• Supabase auth, RLS, storage, and edge function boundaries
• AI provider usage caps, review gates, and traceability
• deployment source/env/smoke proof

Why

The vault/workspace notes repeatedly distinguish UI proof from provider/runtime proof. This section makes that operating standard visible to buyers and reinforces the site's app-rescue positioning.

Validation

• npm run build

Summary by CodeRabbit

• New Features
  • Added a new "Boundary Checks" section containing checklist items for configuration verification, displayed in a responsive grid that adapts to different screen sizes.

📝 Walkthrough

Walkthrough

index.html gains a new "BOUNDARY CHECKS" section (section#boundaries) placed before the existing About section, containing four checklist items (Stripe, Supabase, AI Providers, Deployments). Accompanying CSS adds a two-column grid layout with badge, title, and description styles, plus a responsive single-column override for mobile screens.

Changes

Poem

🐇 Hoppity hop, new sections appear,
Boundaries checked for Stripe, far and near.
Supabase, AI, deployments too—
A grid of two columns, both bordered and true.
The rabbit grins wide at the CSS done right! 🌟

Closing as superseded by #14. Provider/readiness boundaries are now covered by the current AI rescue and service positioning on the survivor branch. This older standalone checklist should not be merged directly into the redesigned page.
